Research
Most individuals with obesity who achieve clinical significant weight loss, are not able to maintain the weight loss in the long term. Meanwhile, most individuals with obesity who undergo bariatric surgery achieve a much larger and sustained weight loss - that is not yet achievable through lifestyle modifications. It is suggested that bariatric surgery's sucess is modulated by favourable changes in the appetite control systems.
Therefore, we investigate how a similar weight loss induced by a very-low energy diet, Sleeve Gastrectomy and Roux-en-Y Gastric Bypass, impacts on homeostatic and hedonic appetite, as well as gut-microbiota. By monitoring these changes, while controlling for magnitude of weight loss, time to achieve weight loss, and level of ketosis, we can illumiate the effect of bariatric surgery it self.
Further, we want to investigate if these initial changes are sustained in the long term, and, if they can predict long term weight loss outcomes.
With these data, we hope to optimize treatment outcomes for obesity, regardless of weight loss modality.
